WINDOW-CHAIR.

Specification of Letters Patent.

Patented May 19, 1908.

Application filed December 4, 1907. Serial No. 405,063.

T 0 all whom it may concern:

Be it known that I, J osnrn W'ARTENBERG, a citizen of the Empire of Germany, residing in Newburgh, in the county of Orange and State of New York, have invented certain new and useful Improvements in \Vindow- Chairs, of which the following is a specification.

This invention relates to an improved window-chair which is intendedto be used for washing windows from the outside so as to prevent accident and loss of life in washing windows of apartment houses and other high buildings; and the invention consists of a window-chair which is made of a main-frame resting on a sill and having means for attaching it at the inside and outside of the wall, a horizontal sliding frame section or seat guided in ways of the main-frame and a guard-frame or back hinged to the outer end of the sliding frame-section and connected by means of chains with the main-section.

The invention consists further of certain details of construction which will be fully described hereinafter and finally pointed out in the claims.

In the accompanying drawings, Figure 1 re resents a side-elevation of my improved window-chair showing the same in position for use on a window-sill, Fig. 2 is a plan-view of Fig. 1, Fig. 3 is a side-view showing the chair folded together for being stored, and Fig. 4 is a lan-view of Fig. 3.

Similar letters of reference indicate corre sponding parts throughout the figures.

Referring to the drawings, a represents the main-frame of my improved window-chair. The main-frame is composed of two side-rails a which are transversely connected by stiffening bars and which are provided with horizontal longitudinal ways w :0 for a sliding frame or seat I) which is provided with transverse bottom rods 6 The inner ends of the rails a of the main-frame are provided with metallic keepers d which carry at their lower ends set-screws (1 having hand-cranks d which are intended to be screwed against the wall below the sill for holding the main-frame firmly in position on the sill. The keepers d are connected to the side-rails and adjustable in vertical direction by thumb-screws (Z ex tending downwardly through the side-rails and screwed into the upper ends of said keepers. The main-frame is also provided with a transverse ledge e of the same thickness as the ledge for the window-sash, so that l the main-frame rests in a horizontal position on the window-sill. The outer end of the main-frame is also connected by a ledge f adjacent to which are hinged stays f which are in inclined position so as to be placed in contact with the outer surface of the wall so as to give an exterior support to the main-frame, while the set-screws furnish the interior support for the same. At both sides of the mainframe are arranged, adjacent to the stays f stationary lugs by which said stays are guided into folded osition and held so, as shown in Fig. 3. l hen the main-frame is placed in position on the window-sill and locked to the wall below the same, the slideframe I) is moved in outward direction by pushing it forward from the inside. To the outer end of the sliding frame is pivoted by means of the pivot-pins 13 passing through the side-rails of the sliding frame a guardframe or back g which is provided with eyes 9 at its upper end so as to be connected by guard-chains g with hooks g attached to the outer side of the side-rails of the main-frame at its outer end a so as to hold the guard frame in upright position when the windowchair is to be used, the guard-frame forming thereby a support for the back of the person washing the sashes from the outside. At the front-part of the side rails a of the mainframe a are also arranged hooks g to which the chains are applied when the slide-frame and guard-frame are moved back into the main-frame so as to be conveniently stored after use.

The slide-frame b is guided in longitudinal ways of the side-rails of the main-frame by means of stationary pins p until the pins arrive at the end of the ways w, While the inward movement of the slide-frame is arrested when moved into the guideways by shorter ways to and the projecting pivot-pins p of the guard-frame.

WVhen the window-chair is to be used it is placed in position and secured to the Wall and sill of the window by means of the outer stays and interior setscrews, after which the slideframe is moved outwardly and the guard frame placed in osition. After use the guard-frame and s ide-frame are moved inwardly into the main-frame. The set-screws are then screwed back so as to clear the win (low-sill and the entire chair is lifted off the window-sill and stored away until required again for use.

Having thus described my inventionLI claim as new and desire to secure by Letters Patent:

1. A Window-chair consisting of a mainframe, means for securing the same on the Window-sill, a sliding frame or seat guided in the main-frame, a guard-frame or back pivoted to the outer end of the slidingjrame, and guard-chains for connecting the guardframe With the main-frame.

2. A window-chair consisting of a mainframe provided with side-rails, means for securing said frame on the Window-sill, a slideframe guided in the main-frame, a guardframe pivoted to the outer end of the slide frame, and guard-chains connecting the top of the guard-frame With'hOOkS on the siderails of the main-frame.

In testimony, that I claim the foregoing as my invention, I have signed my name in presence of two subscribing-Witnesses.

JOSEPH WARTENBERG.
